Your first cube in the scene

Add your first cube via GameObject > 3D Object > Cube.

The GameObject menu

The GameObject menu is the way to add new objects to the scene. Right-clicking an empty area of the Hierarchy window opens the same options. Cube under 3D Object adds a cube to the scene.

GameObject > 3D Object > Cube

The new cube is listed in the Hierarchy as Cube and appears at the center of the scene.

Transform

Every object's position, rotation, and size are held by its Transform. Position is where the object stands, Rotation is which way it faces, and Scale is how big it is. A newly added cube has a Scale of 1, 1, 1.

Cube
Position: X = 0, Y = 0, Z = 0
Rotation: X = 0, Y = 0, Z = 0
Scale:    X = 1, Y = 1, Z = 1

When you change these values in the Inspector, the cube updates its place in the scene right away.

Practice Print the cube info

Define a kupAdi variable holding "Cube". Keep the position values as three int variables: x = 0, y = 0, z = 0. Print the name and the position on one line. Expected output:

Cube konumu: 0, 0, 0

Starter code

Player.cs
using System;

class Kup {
    static void Main() {
        // Kupun adini "Cube" olarak bir string degiskende tut
        // x, y, z degerlerini 0 olarak tanimla
        // Ad ve konumu tek satirda yazdir
    }
}

Sample solution

Player.cs
using System;

class Kup {
    static void Main() {
        string kupAdi = "Cube";
        int x = 0, y = 0, z = 0;
        Console.WriteLine(kupAdi + " konumu: " + x + ", " + y + ", " + z);
    }
}

Expected output

Cube konumu: 0, 0, 0
